SO also has direct rate limiting (40 votes a day). I do think that it makes sense to have a separate rate limit for user-user links; maybe I can vote 100 times a day and have it be normal, but voting even 10 times a day on a particular user might means something funny is going on.
Yes, it would be reasonable to have separate per-user/user link limits. Though the limits could be a function of the number of comments that user made recently—if someone gets into a manic mode and posts dozens of trash comments in a few hours...
Right now, users with sufficiently high karma have access to the vote buttons on the userpages of users with sufficiently low upvote percentage, as far as I can tell to enable this sort of downvoting. It seems likely that exemptions could be baked it to these rate limits just as easily.
